IMPRovED EXTENSION-TABLE.

Specication forming part of Letters Patent No. 59,367, dated November 6,1866.

To all whom it 'may concern.-

Be itknown that I, JOHN B. CURTIS, of Port Henry, in the county of Essexand State of New York, have invented a new and Improved Extension-Table;and I do vhereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying draw ings,forming part of this specification, in which- Figure l is an invertedplan of the extension-table of my invention. Fig. 2 is a longitudinalvertical section taken in the line a Fig. l. Fig. 3 is a verticaltransverse section taken on the line y y, Fig. 2. Fig. 4 is a top View.Fig. 5 is a partial section of a set of table-leaves, on an enlargedscale, showing their attachment to the table.

Similar letters of reference indicate like parts.

lhis invention relates to an improvement in extension-tables; andconsists in arranging extension-leaves in sets, which are foldedtogether within the frame of the table, so that they shall lie under andover each other when the table is closed, and are unfolded when thetable is opened, the extension-leaves being thus connected with thetable instead of being separate, as usual, and therefore more compactand convenient.

Fig. 1 represents the under side of a table when extended, with one setof extensionleaves, Al, unfolded and lying across the frame a a, betweenthe two ends of the top or bedleaves A A, to he supported as usual onfourcorner legs, b b b b, and a central leg, o, fastened to across-piece, B, made stationary under the central sliding frame, a.

There are three sets of extension-leaves, Al, A2, A3, one set, A3, beingtwice the width of either of the other sets-or, in other words,extending longitudinally in the table a distance equal to both the othersets of extensionleaves, as shown in Fig. 2.

.The extension-leaves are cut in three sections, 1 2 3, transversely inrelation to themselves, and longitudinally as regards the table whenextended, as shown in Figs. l and 5; and the sections of the leaves arehinged together so that the outside daps, l and 3, fold above and belowthe center section, 2, when closed within the frame of the table, asshown in Figs. 2 and 3.

The long set, A3, is hinged to a side piece, d. as shown in Fig. 5,which side piece, cl, is hinged to one side of the sliding frame a',that occupies a middle position in the table, and is supported by thecent-ral leg, c, as shown in Figs. l, 2, and 3. By means of the hingedside piece, d, the set A3 is folded down at the bottom of the frame,leaving a space between it and the top or main bed-leaves of the tablefor the other sets of extension-leaves to lie above it when they arefolded and the table is closed, as shown in Figs. 2 and 3. The hingedpiece d also allows the set A3 to rise to the level of the top of thetable when it is extended and the leaves are unfolded, as shown in Fig.3.

The smaller sets of eXtensionLleaves, A1 A2, are hinged to the upperedge of the sliding frames a2, so that when the table is extended andthe sliding frames, to which they are'attached, respectively, are drawnout, the leaves can be unfolded and lie even with the top of the table,as shown in Figs. 2, 3, and 4.

The table may be extended for one or more sets of leaves at a time, pinsbeing provided to hold them in placewhen closed and to take out whenthey are opened. The edges of the extension-leaves are also supported,as usual, by (lowel pins; and, in addition, swinging arms may beattached to the sides of the frames to support the flaps or outsidesections of the extension-leaves when the table is extended and theyare-unfolded.

When the table is fully extended and the central set, A3, is unfolded, across bar is passed through the frame to support the outside sections.

Ha-ving described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

Constructing an extension-table with ex tension-leaves made in sectionsand hinged together and also to sliding frames or draws for-foldingtogether, and lying under 'thc top or bed leaves when the table isclosed, and unfolding even with the top or bed leaves when the table isopened, arranged and operating substantially as herein described.
